Question

Classify each of the following substances as a colloid, heterogeneous mixture, homogeneous mixture, solution, or suspension.

a. Bottled seltzerwater
b. Fog
c. Blood
d. Mint chocolate chip ice cream

Answer 1

Bottled seltzer water is a solution; fog and blood are colloids; mint chocolate chip ice cream is a heterogeneous mixture. a. Bottled seltzerwater

Step-by-step explanation:

The classification of substances into colloids, homogeneous mixtures, solutions, and suspensions is based on particle size and the uniformity of component distribution. Here's the classification for the provided substances:

• Bottled seltzer water: This is a solution, which is a homogeneous mixture of carbon dioxide gas dissolved in water.
• Fog: It consists of water droplets dispersed in air and is a classic example of a colloid.
• Blood: A complex liquid containing cells, proteins, and other substances. It is classified as a colloid due to the protein and cell particles being in suspension, with the components not settling out on standing.
• Mint chocolate chip ice cream: This is a heterogeneous mixture due to the visibly different components, like the chocolate chips and mint ice cream, which do not have a uniform composition throughout.

Answer 2

Bottled seltzer water is a solution, fog is a colloid, blood is also classified as a colloid, and mint chocolate chip ice cream is a heterogeneous mixture, reflecting different particle sizes and behaviors in mixtures.

Step-by-step explanation:

Materials can be classified as colloids, heterogeneous mixtures, homogeneous mixtures, solutions, or suspensions. The classification depends on particle size and the uniformity of the material's composition.

Substance Classification

Bottled seltzer water is a solution, which is a homogeneous mixture of carbon dioxide gas dissolved in water.Fog is a colloid since it consists of tiny water droplets dispersed in air.Blood is a complex mixture; however, for the purpose of classification, it can be considered a colloid due to the presence of cells and proteins in plasma, which do not settle out quickly.Mint chocolate chip ice cream is a heterogeneous mixture due to the visible, unevenly distributed chunks of chocolate and mint within the ice cream base.

Moreover, the distinctions amongst these categories are based on particle sizes. For instance, solutions have particles the size of an ion or small molecule, while colloids have larger particles that remain dispersed in the mixture without settling. Suspensions are even larger and can settle out of the mixture over time.
